The Museum of Cathedral Works (Museo dell’Opera del Duomo) opened in 1986 to showcase the art and sculptures of Pisa. Today, its collection includes works which previously adorned the buildings in the Piazza dei Miracoli. After the big three (the Leaning Tower, the Cathedral and the Baptistery), this is the fourth major landmark to fit into your time schedule. You will find this interesting museum behind the Leaning Tower.
